MICHAEL KARABIN AND JOHN SKOCIOKI'I, OF NEW BRITAIN, CONNECTICUT.

COLLAR-BUTTON.

To all whom it may concern:

Be it known that we, MICHAEL KARAB N and JOHN Snocronn, citizens of Austria, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Collar-Buttons, of which the following is a specification.

Our invention relates to improvements in collar buttons, and the object of our 1111- provement is to produce a collar button that has the same form of contour as certain collar buttons in. common use but which is made of glass instead of metal and which therefore avoids the discoloring effect on the garments with'which the button is used, such as is particularly the case when made of base metal, such glass collar button being suscept1ble of being made in a variety of forms as pertaintaining to the exposed head portlon. Thus the said head portion may b solld, or hollow with the walls of plain glass, 71. 0., wlthout other material, or may be made hollow, with .the interior wall lined with silver or some other metal.

In the acompanying drawing Fig. 5 is a similar sectional view of an-' other modification of our collar button, having the head hollow and the interior wall lined with a layer of silver.

Our improved collar button comprises a base 10 at one end, a head 11 at the other end, and a shank 12 connecting the said ends.

The base 10 is of the usual circular form.

The head 11 is of ball or generally spherical form, the contour corresponding substantially to that of some forms of collar buttons in common use. a,

Thus the mechanical function or operation of our improved collar button corresponds to the function or operation of some forms of collar buttons in common use.

Considering the form shown in Fig. 3, the collar button shown in this figure is made entirely of glass, and of solid form for all of the parts, as shown.

As a special feature of the head structure,

Specification of Letters Patent. Pat-g ted J 17 191% Application filed December 16, 1918.

Serial No. 267,038.

the head 11, which has a rounded end portion 13, is formed by a manipulation of the material when in a pliable condition so as to be shaped to the final form directly involving the use of a die that is of the proper shape to give the desired form for the extreme outer end face of the said head. That is to say, there is no tip or projection at the end after the working of the glass, such as would need to be removed by grinding to obtain the desired rounded form for the end portion 13.

In thecase of the modification shown in Fig. l the head 11 is hollow comprising an outer wall 14. that incloses an open space 15. As a detail, the wall 14L is relatively thin, so that the interior open space 15 is relatively large and represents the major part of the space inclosed by the periphery of the head structure.

The periphery 13 of the outer end is rounded, as in the case of the head 11 and the opposed border wall surface 16 is rounded to correspond, generally concentric.

Thus, as a special feature, the portion 17 of the border wall 14: at the outer end of the head 11 is of substantially uniform thickness. That is to say, the surfaces 13 and.

16 are each continuously and uniformly curved and free from projections or indentations to mar the continuity.

The bearing of this feature or condition is involved in the light effects, which would be affected by such interruption of the continuity of the surfaces 13 and 16, particularly so in the case of the use of clear or transparent glass in making the button structure.

Such plain, clear, or transparent glass is the preferred material for making any and all of the collar buttons shown.

In the case of the modification shown in Fig. 5 the glass structure is made substantially like that shown in Fig. 4:, the head 11 comprising the relatively thin outer wall 14 that incloses the open space 15, the round ed end portion 17 of the wall 14 of substantially uniform thickness with the rounded convex surface 13 on the outside and the concave surface 16 on the inside, and all made of clear glass.

In addition to the glass structure described, the head 11 is provided with a lining 18 that is in the form of a layer of metal, preferably of precious metal, such as silver or gold.

Whatever metal is used would be applied maintain constantly the original condition becauseof the protection provided'by the inclosing glass Wall structure 14, there being no chance for exposure such as to result in tarnishing the surfaceor oxidation.

Because the exteriorsurface of our button is of glass our button will not discolor the clothing With Which it comes in contact and is therefore superior from a sanitary standpoint to buttons of metal generally, particularly to buttons made of base metal, and the head structure, which is the only part that is exposed to view when in use, because of.

the light effects, presents a novel and attractive appearance.

The permanency in character of the head structure of the form having the lining of precious metal is of particular merit.

Weclaim as our invention 1. A collar button made of glass, having a base at one end, a head at the other end, and a shank connecting'the said ends, the said head being of ball-like'or substantially cylindrical form. and having a uniformly rounded outer end surface and the said head being hollow.

2. A collarbutton made of glass as described in claim 1, and theinterior surface of thevvall of the said head being prom t with a;-lining of precious metal.
